I actually did end up hooking the cable up to a USB power supply and tried it with and without the wall plug attached. The power clearly seems to only go to two pins one has 5v on it and the other 5.4v (which are the power outputs of the USB supply and the wall plug.
Originally I just checked the resistance between the ends of the cable to find where the pins went which if there are chips of some sort in between I would have not been able to trace the wires that way.
Although I do want to say the information about where the power goes on the 3rd party cables IS a guess on my part I don't have any of them. BUT if the cables charge while the unit is on based on what I found about where the power goes it makes sense that they are running the power to the normal power in pin. People who hook these cables up to power supplys that can supply large currents (1 amp or more) have seen no problems at all. The people who are having the problems are hooking them straight up to a computers USB ports (I have read about some labtops having problems with the current) or the versa charger which based on an earlier boxwave post someone found it shows that it can also only supply 500mA. In the past I have found that while during normal use thats enough to run the handheld its very possible to use more then 500mA without even charging the battery.
Really I am making more a few more quesses then I like to but its not like Dell is going to answer a question about the adaptor on the axim or internal workings of the axim. If someone has some more information I would love to hear it. I really do like getting proved wrong :)
